*That which is lawful is plain and that which is unlawful is plain and between the two are doubtful matters about which not many people know.

*It is obligatory upon Muslims to engage in lawful actions.

*Lawful and unlawful things are clear.

*There are also doubtful things in regards to permissible acts.

*Other permissible acts are also unclear.

*It is better to avoid doubtful acts.

*Engaging in doubtful acts may incur Allah's displeasure

*For he who deals with the doubtful acts may one day actually deal with the unlawful ones.

Correct Answer: B. 3.0 x 10³Km^-1

Explanation

The temperature gradient is defined as the change in temperature per unit distance.

Given:

Thickness of the rod, Δx = 0.02 m

Temperature at one junction, T1 = 20 °C

Temperature at the other junction, T2 = 80 °C

First, calculate the change in temperature (ΔT):

ΔT = T2 - T1 = 80 °C - 20 °C = 60 °C

Since a change of 1 degree Celsius is equivalent to a change of 1 Kelvin, the temperature difference in Kelvin is also 60 K.

So, ΔT = 60 K.

Now, calculate the temperature gradient:

Temperature gradient = ΔT / Δx

Temperature gradient = 60 K / 0.02 m

To simplify the division:

Temperature gradient = 60 / (2/100) K/m

Temperature gradient = (60 * 100) / 2 K/m

Temperature gradient = 6000 / 2 K/m

Temperature gradient = 3000 K/m

Expressing this in scientific notation:

3000 K/m = 3.0 x 10^3 K/m (or Km^-1)

Comparing this with the given options:

A. 3.0 x 10^2 Km^-1

B. 3.0 x 10^3 Km^-1

C. 5.0 x 10^3 Km^-1

D. 3.0 x 10^4 Km^-1

The calculated value matches option B.

The final answer is 3.0 x 10^3 Km^-1

Explanation

(a) Subsistence farming is a system of farming in which crops and livestock are raised for the farmer's family consumption and not for sale.

(b) Crop farming is the cultivation of both food crops such as plantain, cassava and cash crops such as cocoa, oil palm etc while livestock farming involves the rearing of animals e.g poultry, sheep, and goats.

(c)(i) Granting easy credit to farmers to expand their farms

(ii) Improving the land tenure system and ensuring easy access to land

(iii) Provision of adequate infrastructure such as roads and utilities in the farming areas

(iv) Expanding agricultural extension services to educate farmers on modern farming techniques.

(v) Promotion of all year round cultivation through the provision of irrigation schemes.

(vi) Improving agricultural marketing through the introduction of guaranteed prices

(vii) Providing subsidies on agricultural inputs so that farmers can afford them

(viii) Measures to minimize insect and pest infestation to reduce post-harvest losses

(ix) Provision of storage facilities such as silos and refrigeration equipment

(x) Introduction of high-yielding and improved seeds through research

(xi) Introduction of improved tools and implements through mechanization and modern techniques.

(xii) Organisation of agricultural fairs to make agriculture more attractive.
